It's actually the comic that coined the term. The creator just, for some reason, decided to use weirdly racial language to depict it, and imply the prejudice is based on evidence.
Which is kind of weird.
As is pretending it isn't, when you could just say "yeah it's a little problematic" and move on with your life.
Let me guess, your country has deep seated issues with racism the population either refuses to acknowledge or "solves" by simply not letting other races in?
This comic was made by an American, in reference to an American issue, so pretending the American viewpoint isn't valid by virtue of being American is just, you know.
Stupid. Intellectually dishonest. Dare I say, pig headed.
